This one is very simple.
create a simple equation to find out
15 = 12 + x
subtract 12 from each side
x= 3
the missing number is 3
or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.
hope I helped
ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.
Ok so we know that each combo meal is $5. So 24 x 5 = $120
$6 service charge has to be divided by 120.
6/120 = 0.05
5%
$20
I got it by dividing 12 tickets÷3 which equals 4. Then I multiplies 4×$5= $20
